SW-243

www.DataSheet4U.com Reflective GaAs SP4T Switch DC - 4 GHz Features Low Insertion Loss: 0.7 dB Typical Fast Switching Speed: 4 nS Typical Ultra Low DC Power Consumption Small Package Size: 0.250” Square RF1 SW-243 V3 Functional Schematic GND RF COM GND RF4 Description M/A-COM’s SW-243 GaAs MMIC SP4T switch is packaged in a CR-4 surface mount ceramic style package. The SW-243 is a reflective switch, optimized for low insertion loss. The CR-4 package is hermetically sealed, making these switches ideal for space, military radios, or other environmentally harsh applications. Typical applications include synthesizer switching, switch matrices and filter banks in systems such as military radios, and space equipment. The SW-243 is fabricated as a monolithic GaAs MMIC using a 1.0 micron MESFET process.
